Filter job postings and draft application essays from tagged experience blocks

Lee, a recent graduate in Korea, adapted a job search guide another Claude Code user had shared on X and rebuilt it for entry-level and internship roles. The setup has three parts. A criteria file holds the roles Lee wants, what rules a posting out and how to score it; postings from email alerts get a free first pass from Gemini and are then scored by Claude in a fixed format for review. Lee's experience is written as nine STAR blocks, each tagged on four axes, with a one-line index the agent reads before opening only the blocks it needs. A drafting flow matches a posting's required skills to the blocks and writes an application essay, with a rule that no fact may appear that is not in the blocks. Everything is kept in git.

Reviewing postings went from more than half a day to about 20 minutes. After building it Lee submitted two applications and reviewed two more that were deliberately not sent. The agent made mistakes along the way: it turned a mention of a doctoral program into a PhD in Engineering, and assumed a file it had once generated existed in the folder. Each became a written rule.

Borrowed prompts did not fit an entry-level search, so Lee rebuilt them. Uncertain facts are handled one of three ways: the user's exact words, an estimate with reasons that gets approved, or a [NEEDS CHECK] mark. Splitting files by kind of work keeps the agent from loading everything.
